Affiliate link to web page rather than product

Hi All,

I want to link my affiliate link to a normal web page rather than the product in WHMCS.
Is this possible.

Support told me it was a simple adjustment to aff.php but it doesn't look as "simple" as suggested.

So, rather than this:
AffiliateLinkCode]&pid=34 which thanslates in to the following link:
<a href="http://www.easydomains.com.au/billing/aff.php?aff=002&pid=34"><img src="https://easydomains.com.au/images/banners/app-banner-120x60.png" style="height:60px;width:120px;" border="0" alt="EZiApps - $29.95 per month - push notification - free mobile site - fully hosted - stats - multi-platform publishing including iPhone, iPad, Android and Windows Mobile" /></a>

I would like the code to link to this:
http://easydomains.com.au/iPhone-And...australia.html

Any suggestions would be tremendously appreciated but please note that I'm a simpleton :idea:...
